Florida pollen review.
Pollens in Florida are most numerous in January through March and approximately 82% are tree pollens. Two of the most common trees, southern red cedar and laurel oak, do not have commercial extracts. There are relatively low pollen counts for grasses and weeds, but the season is prolonged. The low counts do not indicate that these are not important allergens since in Florida children with allergies show a high reactivity rate to these allergens. Numerous grasses that are wind-pollinated and possible allergens have not been studied. In the Urticaceae family, there is no extract for Parietaria floridana. Acalypha has not been evaluated in this region and is also present in the air surveys using more efficient sampling techniques.
